The SSI SI-117A Mobile Rack for 2.5" notebook IDE drivesThis is a unique mobile rack subsystem. Installed in a computer, it will allow the use of a 2.5" notebook drive as the removable. This is helpful when you want to load from a customized image source, eliminating the need custom-installing software onto the notebook manually, a common procedure after you use a manufacturer's restore backup CD. You can remove the notebook harddrive from the notebook, and put it in the mobile rack caddy, and then slide it into the frame that sits in the desktop, and begin the copy process from a source into that removed notebook drive.

The frame is made out of metal. It is a 3.5" width device, it can be mounted in a 5.25" bay with the use of a floppy adapter. The caddy part is entirely made of plastic, and was designed for containing a 2.5" harddrive permanently, the shells must be screwed together tight to house the 2.5" drive. It may be difficult to use for bulk loading notebooks, as the pieces are loose if it isn't screwed together. It's also possible to cannibalize the whole device just to get the adapter that converts from a mini-ide to the standard ide 40-pin.
